FOLDING UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 410,114, dated August 27, 1889. Application filed February 9, 1889. Serial No. 299,249. (No model.)

To a. whom it may concern:

Be it known that I, ELIJAH J. PRESTON, a citizen of the United States, residing at Dayton, in the county of- Montgomery and State of .Ohio, have invented certain new and useful Improvements in Folding Umbrellas, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improve ments in folding umbrellas, sunshades, or parasols; and it has for its objects to directly and securely brace the folding-ribs of such articles at their joints, when raised, by means of a series of sub-braces, and to provide for bringing the sub-braces into folding position when lowered or closed, as more fully hereinafter set forth.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a sectional view of a portion of the skeleton of an umbrella, showing the parts in the position they assume when raised or opened. Fig. 2 represents a View, partly in elevation and partly in section, showing the parts in a closed and folded position. Fig. 3 represents a perspective view showing the. means of connecting the folding ribs, so as to slide with respect to each other; and Fig. at represents a detached view, partly in section and partly in elevation, showing the relative arrangement of the folding ribs, the sub-brace, and the ordinary brace.

The letter A indicates the stick or staff of the umbrella, which is constructed in two parts and connected by means of a link a, as is usual with the sticks of parasols, sunshades, and the like, to permit folding the same; and 1) indicates the sliding sleeve ordinarily employed to hold the parts of the stick in an extended position.

B indicates the usual radially-slotted collar, secured near one end of the stick to which the ribs are pivoted. Each rib is constructed in two parts O -D, the upper or outerrib being grooved or fluted longitudinally, the groove being rectangular, semicircular, or polygonal in cross-section to suit convenience. The free end of each of the outer or upper sections O of the ribs is constructed in the shape of or provided with a short sleeve 1), through which the upper end of the corresponding lower section slides in and out of the longitudinal groove in said upper section. The upper end of each lower section before mentioned is curved inwardly, as indicated by the letter 0, the said curved end extending through an aperture on the inner side of a sleeved, fitting loosely on the upper or outer sections of the ribs, so as to slide thereon.

The lettersE F indicate the main and supplemental or sub braces, respectively, which are hinged to the hooked ends of the lower sections of the ribs, the ends of the respective braces being slightly curved toward each other, and the end of one of said braces bifurcated, so as to straddle the other, and thus permit the said braces to move freely without interfering with each other. The braces E at their inner ends are pivoted to the radially-slotted ring of the ordinary runner G, which is arranged to slide on the stick, as usual, and the inner ends of the sub-braces F are similarly connected to the ring of a supplemental runner H, which is arranged to slide on the staff between the runner G and the collar to which the ribs are pivoted.

The letter I indicates the ordinary latchspring, by means of which the runner G is supported when the ribs are distended and the umbrella raised, and K a similar latchspring which supports the runner H when the parts are in such position. The spring I is located in the usual position, but the spring K is located just below the collar 13, so that the runner H may rest closely against its under side when the umbrella is raised.

It is evident that a pin or other fastening device may be substituted for this latchspring withont departitig from the spirit of my invention.

The 'operation of my inventionisas follows: The parts being folded in position, as shown in Fig. 2, to open the umbrella and distend the same, the parts of the stick are brought in line, as shown in Fig. 1, and are held in posit-ion by the sleeve 1), which is slipped over the joint, as usual. The runners are then drawn simultaneously toward the handle until they reach their limit in that direction,

Too

drawing the braces and lower sections of the ribs With them. WVhen in this position, the runners are simultaneously elevated until they pass, and are held by the latch-springs I K, distending the parts, as shown in Fig. 1. To return the parts to a folded position, the runners are again drawn toward the handle until they reach their limit in that direction, and then by lightly grasping the ribs With one hand and moving the runners simultaneously from the handle with the other the runners, braces, and ribs will assume the position shown in Fig. 2, after which the stick may be folded, as shown in said figure.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is The combination, with a jointed stick pro- ELUAH J. PRESTON.
